Groeben family
The Groeben family (also Gröben or von der Groeben) is the name of an old German noble family, originating in the Altmark region. The lords von der Groeben belonged to the nobility of the Archbishopric of Magdeburg, and moved from there to the Margraviate of Brandenburg, then to East Prussia. Members of the family held the title of Count in Prussia, granted to them on 19 September 1786 by King Frederick William II. Various branches still exist today.
The Genealogisches Handbuch des Adels mentions another family of the same name, whose ancestor was Hans Gottlob Greben (1724-1777), a lieutenant under the Kingdom of Poland, the Electorate of Saxony and the Kingdom of Prussia. His son Friedrich Wilhelm (1774-1839) was a Prussian lieutenant general, and he and his descendants used the name and coat of arms of von der Groeben without objection.
